Nice design, very clean, very Diggy.
Not sure if it was not 2.0 before though, functionality wise. Which would make it 2.1 now. And if SEOBook is 2.0, does that make Threadwatch 3.0?
Does adding rounded boxes and little circle headed men make it 2.0?
If so, Fisher Price little people were 2.0 30 years ago :)
